SPECIFICATION forming part of Letters Patent No. 599,816, dated March 1,1898.

Application filed February 8, 1897. Serial No. 622,499. (No model.)

To a/ZZ whom it may concern:

Be it known that I, WILLY WALLAcH, a citizen of the United States,residing at Paris, France, have invented certain new and usefulImprovementsl in Brushes, of which the following is a specification.

My invention (for which protection has been secured in France in thename of Charles Loonen, with my knowledge and consent, by a certificateof addition, dated January 25, 1897, to the original patent, No.237,750,dated April 13, 1894) relates to improvements connected withbrushes generally, but is more particularly applicable' to a ner classof brush-such as tooth-brushes, nail-brushes, and other like brushes forpersonal use; and the invention has special reference to improvementsintroduced in the kind of brush for which Letters Patent of the UnitedStates were granted to me under date of July 17, 1894, No. 523,058. v

The improvement has mainly reference to the formation of the brush-headand to the connection of that head to the handle when it is a questionof manufacturing toothbrushes and other like ne brushes having alhandle. ,Y

The object I have in view to accomplish is to lessen the cost ofmanufacture of that kind of brush, while at the same time producingaperfectly well-finished article which is very strong and the head ofwhich, being solid, can be readily utilized for rapidly and economicallyattaching the bristles.

In my aforementioned patent I have described a brush-handle constitutedby a hollow celluloid shell made of a single piece, into which isarranged a lling composed of a hard portion-say bone-lling out the headand capable of receiving the bristles, and of a shank or stem of anysuitable metal rigidly connected to the bone or other hard materialflllin g up the head by means of a metal sleeve or otherwise. Thismethod, while perfectly well suited for proper end attachment of thebristles, calls for a labor which, if not com? plicated, at leastremains more or less expensive, since it requires the following mainoperations: first, preparation of a celluloid 5o shell and a bone orother hard filling for the head; second, connection of such filling tothe shank or metal stem of the handle; third, introduction of thefilling into the shell; fourth, closing up the shell at the head end,through which the introduction takes place; fifth, sealing or cementingthe stem or filling into the handle with a plastic material previous tothe final closing up of the remaining otherend of the shell.

. The new method of manufacture which I 6o have. devised dispenses witha considerable amount of these operations and of the labor attendantthereupon, and, besides reducing the cost-price, it enables meto utilizewith advantage in the formation of the brushhead itself the wasteproduced in the manufacture of certain celluloid articles.

The annexed drawing shows in section a tooth -brush made in accordancewith the present improvement. 7o The brush is substantially constitutedby a head ct, for the reception and fastening of the bristles b, and bya handle c. The handle c is formed of a hollow shell molded fromcelluloid in the manner referred to in the aforementioned patent or inlany other suitable manner, the said shell being subsequently filled upby a filling d of any suitable powdered material, compressed or not,

whether wet or dry, capable of giving con- 8o sistency and resistance tothe article-such, forinst-ance, as a mixture of plaster-of-paris andwater. The head a is formed of a piece of celluloid, assuming a suitableshape for the purpose required and obtained by molding or otherwise.`The lower end of the head et' surrounds the upper end of a stem f, ofany suitable metal or rigid material, embedded in the celluloid duringthe molding operation or otherwise. Suitable projections, 9o teeth, orlike asperities,such as f',are formed in any suitable manner on theembedded end of the stem ffor the purpose of increasing the adherencethereof to the celluloid.

At the lower end of the head a, surroundg5 ing the stem end f', isformed an offset a', engagingv and tting exactly theupper open end ofthe shell c. If desired, the connection between the head-offset a andthe shell c may be perfected or increased by the use of cement roo orany other means.-

When the head has been introduced and secured into the end of the shell,as shown in Vhat I claim, and desire to seeure by Letthe drawing, theshell is lilled up through the ters Patent, is- 15 bottom hole c withany suitable filling d, as A brush comprising a brush-head, a shankdescribed, thereby imparting consistency and or stem for said head, ahollow handle and a 5 stiness to the handle and sealing the stemf fillertherein, in which said shank or stem is firmly. The bottom holeecan thenbe plugged anchored, for the purpose set forth. by a cemented disk ofcelluloid. On the stem In Witness whereof I have hereunto set my 2o fare likewise formed asperities, such as f2, hand, this 26th day ofJanuary, 1897, in presfor anchoring the stem to the filling.
